The pipelines (400m²) of a power generation plant in South Korea were suffering from severe corrosion damage and required to be re-coated.

Previous conventional paint systems required to be re-coated after only 2 years in-service; at high refurbishment cost. The client was therefore looking for a system which could offer long-term maintenance-free protection as opposed to the short-term solutions they previous had through the use of conventional paints.

There could be no disruption to the working plant; therefore grit blasting was not permissible. The project also had to be carried out in high humidity. Water jetting was utilised as the surface preparation method.

Significant time and cost savings were achieved by utilising water jetting as the surface preparation method. Due to the satisfaction of the customer, the same system has now been specified for a similar pipeline external project (over 1500m²) for late 2017.

By utilising this unique system, the following benefits were achieved:
